Every agency now says AI. The model underneath has not changed.
The traditional agency bills you for the pyramid: juniors learning on your money, account layers between you and the people doing the work, and a scope written to protect the retainer. Bolting a chatbot onto that model does not update it. It just makes the deck longer.
Most AI projects fail the same way, and for the same reason. Tools bought off the shelf, generic by design, bought for the press release rather than the results. The problem was never the technology. It is who is using it, and what they point it at.
